Application led .Tune '7,1894- Serial No. 5131806- (NO 11105010 A Y To@ZZ whom t may concern:

Be it known that I, FREDRIOK A. MATHEWs, a citizen of the United States,residing at La Harpe, in the county of Allen and State of Kansas, haveinvented a new and useful Windmill, of which the following is aspecistruction and combination and arrangement of parts'which will bethe' more fullyvv den scribedand finally embodied in the claims.

In the accompanying drawings: Figure l represents a side elevation of myinvention; Fig. 2, a plan view; Fig. 3, a bottom plan of the platform;Fig. 4, a vertical section; Fig. 5, a detail perspective of one of thewindblades, showing it attached to the hub of the wheel; Fig. 6, adetail perspective showing the construction of the platform; Fig. 7, adetail perspective showing the devices for attaching the adjustablevane.

The reference numeral 1 indicates the framework of the tower, which may,of course, be of anypconstruction. The upper ends of the verticalstandards of the frame 1 are rigidly secured to thedownwardly-projecting studs 2, of the circ-ular plate or disk 3. Thisdisk 3 is disposed horizontally and provided with a central orifice through which the barrel 4 passes, while itis strengthened by the ring 5,arranged on its upper side and embracing the barrel. Formed in the ring5 and disk 3, and vertically aligned in each, are the openings 6, inwhich the wedge-key 7 is arranged 1 and by which the barrel is to thedisk and ring. y

The barrel 4 is hollow throughout its length and provid/ed at itsupperend with a block 8, which is secured rigidly in place and serves toclose said end. Formed in the block 8, and axially coincidentwith thebarrel, is the passage 9, in which the drive-shaft 10 of the marigidlyconnected chine is arranged, so as to be capable of ro-v 'Fliese endsare,

extends vertically throughout the length of the barrel and is seated, atits lower end, in the cup-bearing 11, formed in the block 12, the blockbeing arranged, in turn, in the lower end of the barrel and rigidlysecured thereto and to the brace 13 of the frame 1.

Formed in the barrel 4, just below the disk 3, is thehorizontally-elongated slot 14, which is adapted to furnish access tothe small beveled gear 15, fixed to the shaft 10. YThe gear 15 is of adiameter which will make it possible to pass itthrough into the interiorof the barrel, and it is by this means that the parts f are placed inposition. The gear 15 meshes with therlarge crown gear16, mounted uponthe stub-shaft 17, and this is, in turn, iixed'to the lower end of thebarrel by screwing it therein, or Y otherwise. By these means the motionand power attending the shaft 10 are trailsmitted to the wheel 16, andfrom the wheel 16 the power is communicated to the pitman 18, throughthe medium of the crank-pin 19, fixed lto the wheel, and pivotallyconnected to the upper end of the pitman. The pin 19 is secured to thewheel16 by means Vof one of the series of openings 20, which arearranged in radial alignment, and by this means the stroke of. thepitman can be made long or short, to

'4, is the platform 25, which is circular in shape and centrallyperforated to permit mounting it. Located in the opening inthe platform25, and rigidlyl secured therein, is the bushing 26, which is formedwith a downwardly-eXtending portion 26a and with a rabbet groove 27 onits upper side, in which groove the collar 28 is adapted to lie.

The collar 28 serves to hold the platform 25 in place, and it is itselfretained byv means of the key 29, passed'diagonally through it andengaging the block 8. The platform 25 is preferably formed of sheetmetal and pro` IOO vided at its periphery with the vertical (lange orwall 30, which extends fora distance equal to little less than one-halfthat of the periphery of the platform, and is of a height equal to aboutthe radius thereof. Formed at one end of the ange or wall 30, andextending radially therefrom, is the offset or secondary flange 3l, andthis is adapted to serve as a vane or guide for the wind, whereby it is1o guided into engagement with the wind-wheel,

as will be hereinafter described.

Formed in the platform 25, and extending from the olf-set 31 to a pointnear the center of the platform, is the downwardlyinclined side 32,whichhas one side extending radially on the platform, while the remainingside eX- tends olf laterally from the rstand at right angles thereto tothe periphery of the platform. Rigidly secured to or formed integral V2o with the periphery of the platform,and extending around the edge ofthe portion 32, is the wing 33, which curves outwardly and up` wardlyand operates, with the olfset 3l, to`

guide the wind up the incline 32 and into enf 5 gagement with the wheel.

The platform is revolubly mounted so that it will ne capable of`adjusting itself to the direction in which the wind is blowing and thisadjustment is effected by the vanes 3e 34 and 35, one of which is rigid,while the companion is pivoted so that its angle may be varied for ahereinafter-described purpose. The vane 34 is the rigid vane, and isriveted or otherwise secured to the under side of the 3 5 platform bymeans of the attached arm 36, which extends downwardly from the platformand is rigidly connected to the vane, whereby the Vane is located belowthe plane ot' the platform.

The disposition of the vane 34 is approximately radial, and itis locatedat a peripheral point on the platform, about one-half the distancebetween the wing 33 and the end of the flange 30, which end is oppositethe one having the offset 3l. The vane 35 is arranged at the said end ofthe iiange 30, and normally projects radially from the platform. Thevane is pivoted to the stud 37, xedin turn to the lower side of theplatform, by means of 5o the arm 38, rigidlysecured to the Vane at oneend and to the disk 39 at the remaining end. The disk 39 is providedwith a central opening which embraces the stud 37, whereby it ispivotally mounted, while its movements are limited within the extent ofa quadrant by means of the peripheral slot 40, operating with the pin4l, fixed to the platform.

Rigidly secured to the disk 39, and concentric therewith, is the groovedpulley 42, to

6o which the cable 43 is fixed and over which it operates. The cable 43is ixedto the pulley 42 by means of the pin 44 and proceeds aroundone-half of the periphery of the pulley and is connected to theretractile spring 45. The spring 45 is connected at its remaining `endto the spindle 46, which is passed through an opening in the arm 47,depend ing from the platform and screw-threaded throughout its length.Operating on the screw -threaded portion is the nut 48, by which thespindleis held from passing through the opening in the arm 47, and bywhich the spindle may be adjusted so as to increase or diminish thetension of the spring 45. By these means the pulley 42, and consequentlythe vane 35, is given a tendency toward the flange 30, the vane beingcapable of moving against the tendency of the spring and to ward thecompanion 34. This movement is effected by means of the ptman 49, whichis pivoted to thepulley 42, and which extends across the under side ofthe platform to the short arm of the bent lever 50. The lever 50 ispivoted at itsbendto the arm 5l, rigidly secured, in its turn,;to theplatform 25, and depending downwardly therefrom.

From the `arm lthe long arm of the lever 50 extends diagonallydownwardlyand normally lies alongside the barrel 4 and `in engagement with theupper end of the collar 52. The collar 52 is loosely mounted on thebarrel so as to be capable of vertical movement thereon, `and thismovement is eifected by means of the .vertically-reciprocatiug ,rod 53,arranged in the opening 54 of the disk 3, and in the eye 54L of thelowerend of thebarrel 4. The lower end of the rod 53 `is providedwith anapertured and horizontallvextending arm 55, to which the cord `orcableis connected.

From the arm 55 the cable 56 extends upwardly and over the pulley 57 fofthe barrel 4, `and thence `downwardly to the ground `within reach ot'the attendant. Thus it will be `seen that the collar52 may be raised orlowered at will, which willresult in a raising of the longarm of thelever 50, and in a consequent turning ofthe vane 35, whereby it may bemoved toward the companion vane and its relation to the platform andsaid vane changed. This will result ina change in the relative positionsofthe platform and windwheel.

Thus, when the Valles are in their normal positions, the wind will passover about onehalf of the platform and therefore exert all the infiuencepossible on the wheel mounted on it, the remaining half of the wheelbeing covered by the flange 30. If, however, the vane 35 be movedtowardits companion, the oifset 31 will be thrown to the right, so as tocut olf the wind from the wheel, and to cause it to engage onlywith thatpart which is yet to the right of the said offset. This adjustment maycontinue until the wheel is nearly completely shaded from thewind, andwill result in the varying ofy the speed at which the wheel is moving.

58 indicates two braces which are attached one to the stud 37 and theremaining one to the arm 51, and have their other ends joined to eachother by means of the pin 59, passing into the platform 25. The inclinedportion 32 is also braced by means of the arm GO, which extends fromsaid portion to the plane IDO ITO

portion of the platform. The shaft lO extends above the block 8, andtheplatform v25, and to a point about level with the upper end of thefiange 30, where it is provided with `the wind-wheel.x Y

The Wind-Wheel consists of thehub 60a,

' which is cylindrical in shape and perforated longitudinally so that itmay be lixed to the shaft 10. 61 indicates the blades of the wheel, andthese are secured in place by means of the ribs 62, formed integral withor rigidly secured to the hub, tbeblades being bolted or riveted to theribs. The blades are disposed horizontally and are V-shaped incross-section, so that they will more effectually gather and retain thewind. 'I he number of the blades may be any whichwill suit theexigencies of the occasion orI the convenience of the manufacturer, andthe blades are of a height about equal to the height ofthe ilange 30.

It will be' understood that the number of the blades 61 will notapproach that of the blades vof the feathering-blade wheel, sincey thetwo kinds operate on different principles, as will be understood. Afurther point regarding the principle of the invention lies in the factthat the machine is adjusted lto the direction of the wind withoutmoving the wheel, but by moving a shieldor guard, and thereby coveringand exposing the necessary parts, as will be apparent from theaforegoing specification. Y

The operation and use of my invention will not need any detaileddescription, since it does notdiffer from that attending otherwindmills, and is, therefore, known. It will suffice for me to say thatthe machine is well adapted for driving all kinds ofmachinery,

to which windmills are generally applicable.

Theadjustment of the vane 35 is retained by securing-the operating lcordat the `proper position to the frame l, or to any other convenientobject.

Having described my invention, what I claim is- I 1.- In VawindmilL-,the combination with a frame, of a barrel extending verticallyand rigidly and immovably mounted thereon, a
